[help] thermodynamics question

    [help] thermodynamics question!!

    1. The problem statement, all variables and given/known data

    Initially, a piston-cylinder has a volume of 120L and contains a saturated
    liquid-vapour mixture of water at 150°C, in which 86% of the water is in the
    liquid phase. The water is heated at constant pressure until it is saturated
    vapour. Determine the heat required for this process. Also show the
    process in a T-v diagram.


    2. Relevant equations

    1. i think the table A-4 and A-5 is required
    2. h=hf + x hfg ??

    3. The attempt at a solution

    dont know how to start.

    Re: [help] thermodynamics question!!

    I think you are missing two important facts.

    One is that people here volunteer their time to help. Complaining that they aren't working hard enough or fast enough to suit you isn't likely to make anyone more likely to help you. Who wants to help an ingrate with a sense of entitlement?

    The second is that we insist that people who ask questions make an attempt at solving them.
